DERIVED DEFORMATION RINGS ALLOWING CONGRUENCES

Résumé

We generalize a result of Galatius and Venkatesh ([GV18, Theorem 14.1]) which relates the graded module of cohomology of locally symmetric spaces to the graded homotopy ring of the derived Galois deformation rings, by removing certain assumptions, and in particular by allowing congruences inside the localized Hecke algebra.
